style="text-indent:25px">太陽電池的主柵是不確定數(shù)目的，這都是隨時代而變換的，以前是兩主柵，后面有三主柵，還有五主柵，其實也有研究過無主柵的，主柵的主要作用與細(xì)柵類似，都是收集載流子，但是呢，主柵的數(shù)量及寬度是要追求一個比較好化的，既要滿足足夠多和粗來講全部的有效載流子收集起來，又要盡可能的少和細(xì)來盡量減少對太陽光的阻擋作用。因此需要在這之間找一個平衡。因為背面不涉及到采光問題（普通電池），所以一般設(shè)計成全鋁背場，但是也得要載流子導(dǎo)出來啊，所以會有背銀的存在，全鋁背場和背銀都是背電極。主柵和背面的背銀都是為了焊接用的，你看到的封裝好的電池，前面的主柵上是焊了一條焊帶的，背面也是，背銀的作用就是為焊帶焊接導(dǎo)出載流子而用的，需要注意的是細(xì)柵和主柵是絲網(wǎng)印刷印上去的，而你看到封裝好的電池的主柵上覆蓋了一層焊帶，這是焊上去的。至于你說的正極負(fù)極，這跟柵線的數(shù)目沒有關(guān)系，這主要與電池片的類型有關(guān)，P型電池片的正極是背電極，前電極（主柵細(xì)柵）就是負(fù)極。遼寧單晶太陽能電池片公司太陽能電池片和太陽能電池板的區(qū)別？</p><div

該工藝用于太陽能電池片生產(chǎn)制造過程中，通過化學(xué)腐蝕法也即把硅片放在氫氟酸溶液中浸泡，使其產(chǎn)生化學(xué)反應(yīng)生成可溶性的絡(luò)和物六氟硅酸，以去除擴散制結(jié)后在硅片表面形成的一層磷硅玻璃。在擴散過程中，POCL3與O2反應(yīng)生成P2O5淀積在硅片表面。P2O5與Si反應(yīng)又生成SiO2和磷原子，這樣就在硅片表面形成一層含有磷元素的SiO2，稱之為磷硅玻璃。去磷硅玻璃的設(shè)備一般由本體、清洗槽、伺服驅(qū)動系統(tǒng)、機械臂、電氣控制系統(tǒng)和自動配酸系統(tǒng)等部分組成，主要動力源有氫氟酸、氮氣、壓縮空氣、純水，熱排風(fēng)和廢水。氫氟酸能夠溶解二氧化硅是因為氫氟酸與二氧化硅反應(yīng)生成易揮發(fā)的四氟化硅氣體。若氫氟酸過量，反應(yīng)生成的四氟化硅會進一步與氫氟酸反應(yīng)生成可溶性的絡(luò)和物六氟硅酸。 </p><p> ⑤峰值功率(pm)：峰值功率也叫比較大輸出功率或比較好輸出功率。峰值功率是指太陽能電池片正常工作或測試條件下的比較大輸出功率，也就是峰值電流與峰值電壓的乘積：pm===im×um。峰值功率的單位是w(瓦)。太陽能電池的峰值功率取決于太陽輻照度、太陽光譜分布和電池片的工作溫度，因此太陽能電池的測量要在標(biāo)準(zhǔn)條件下進行，測量標(biāo)準(zhǔn)為歐洲委員會的101號標(biāo)準(zhǔn)，其條件是：輻照度lkw／㎡、光譜aml.5、測試溫度25℃。 </p> <p> ⑥填充因子(ff)：填充因子也叫曲線因子，是指太陽能電池的比較大輸出功率與開路電壓和短路電流乘積的比值。計算公式為ff=pm/(isc×uoc)。填充因子是評價太陽能電池輸出特性好壞的一個重要參數(shù)，它的值越高，表明太陽能電池輸出特性越趨于矩形，電池的光電轉(zhuǎn)換效率越高。 </p> <p> 串、并聯(lián)電阻對填充因子有較大影響，太陽能電池的串聯(lián)電阻越小，并聯(lián)電阻越大，填充因子的系數(shù)越大。填充因子的系數(shù)一般在0.5～0.8之間，也可以用百分?jǐn)?shù)表示。 </p> <p> ⑦轉(zhuǎn)換效率(η)：轉(zhuǎn)換效率是指太陽能電池受光照時的比較大輸出功率與照射到電池上的太陽能量功率的比值。即： </p> <p> η=pm(電池片的峰值效率)/a（電池片的面積）×pin（單位面積的入射光功率），其中pin=lkw／㎡=100mw／cm2。 </p> <p> <br /> 太陽能電池片連接問題！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

太陽能電池需要一個大面積的PN結(jié)以實現(xiàn)光能到電能的轉(zhuǎn)換，而擴散爐即為制造太陽能電池PN結(jié)的**設(shè)備。管式擴散爐主要由石英舟的上下載部分、廢氣室、爐體部分和氣柜部分等四大部分組成。擴散一般用三氯氧磷液態(tài)源作為擴散源。把P型硅片放在管式擴散爐的石英容器內(nèi)，在850---900攝氏度高溫下使用氮氣將三氯氧磷帶入石英容器，通過三氯氧磷和硅片進行反應(yīng)，得到磷原子。經(jīng)過一定時間，磷原子從四周進入硅片的表面層，并且通過硅原子之間的空隙向硅片內(nèi)部滲透擴散，形成了N型半導(dǎo)體和P型半導(dǎo)體的交界面，也就是PN結(jié)。這種方法制出的PN結(jié)均勻性好,方塊電阻的不均勻性小于百分之十,少子壽命可大于10ms。制造PN結(jié)是太陽電池生產(chǎn)**基本也是**關(guān)鍵的工序。因為正是PN結(jié)的形成，才使電子和空穴在流動后不再回到原處，這樣就形成了電流，用導(dǎo)線將電流引出，就是直流電。單晶硅太陽能電池片和多晶硅太陽能電池片的區(qū)別！安徽光伏太陽能電池片</p><p style="text-indent:25px">逆電流太陽能電池片有什么壞處？遼寧硅太陽能電池片焊接</p><p> 現(xiàn)在工業(yè)生產(chǎn)太陽能電池片的硅片，都是P型襯底，意思是之前已經(jīng)摻雜三族元素了，我們只需要進行磷擴散，就可以形成P-N結(jié)。 </p> <p> 以n型半導(dǎo)體為底板結(jié)構(gòu)的結(jié)晶硅類太陽能電池與以p型半導(dǎo)體為底板的結(jié)構(gòu)相比，前者對雜質(zhì)的抵抗性更大，在理論上更易提高能量轉(zhuǎn)換效率。不過，此前許多結(jié)晶硅類太陽能電池幾乎都采用以p型半導(dǎo)體為底板的結(jié)構(gòu)。原因是在較厚的p型半導(dǎo)體上能夠形成非常薄的n型半導(dǎo)體層。 </p> <p> 德國弗勞恩霍夫太陽能系統(tǒng)研究所（Fraunhofer ISE）宣布，該機構(gòu)研制的以n型半導(dǎo)體為底板，然后在其上面形成較薄的p型半導(dǎo)體層的單晶硅太陽能電池，其能量轉(zhuǎn)換效率達到了23.4％。太陽能電池單元面積為2cm見方。遼寧硅太陽能電池片焊接</p><p
